Those are the only ones I could think of too.

However, I do recall reading that John Young trained to be the "emergency" spacewalker on STS-9 along with Parker if one had been required (say to close the doors or something) due to his prior EVA experience.

Culbertson and Bowersox got to do EVA's on their ISS flights.

Why didn't McDivtt do an EVA on Apollo 9? Was it ever considered? Were two PLSS carried in the LM on that flight?

I don't think one was scheduled for safety reasons. Scott did a planned "stand-up" while RS was out of the LM but (I believe) that was the only 2-man space walk before Skylab.

No, Yeliseyev and Khrunov did an EVA transfer from Soyuz 5 to Soyuz 4 in January, 1969. At the time, Soyuz did not have an internal transfer tunnel.

I believe that an emergency EVA transfer from the LM to the CSM was a contingency for all flights with the LM (in case re-docking wasn't possible). In fact, that is what Schweickart was supposed to demonstrate on Apollo 9 before his motion sickness resulted in a curtailment of the EVA. As such, I presume there was at least part of a PLSS for McDivitt (not the full lunar gear, but the upper smaller portion of the PLSS) in case of such a necessity.

Both LMP Schweickart and CDR McDivitt would have used the oxygen purge system (OPS)--the small upper component atop the PLSS--to provide them with 30 minutes of oxygen for such an emergency transfer from LM to CM. I have recently seen old footage of each of them training in the Manned Spacecraft Center's Water Immersion Facility (WIF) for such an eventuality in the weeks before their Apollo 9 flight.

I had always thought CDR Young was also designated for any STS-1 contingency EVA, such as to close the payload bay doors. But checking the STS 1-5 mission reports published by Apogee Books and Robert Godwin, I see it was PLT Crippen who was the prime EVA crewmember on STS-1, and apparently PLT Fullerton on STS-3--not their Apollo/Skylab EVA-experienced CDRs Young, Lousma and Mattingly, and Apollo EVA-trained Engle.

Funny I had that wrong for the last 3 decades!

Yes, of course the Oxygen Purge System! I should have known that.

Was the hatch in the tunnel open or closed during the EVA? Would it matter? Both the CM and the LM were depressurized.
